Description

Application

<ul>
<li><strong>Environmental Monitoring</strong>: Nitrite tests are widely used in environmental monitoring to measure nitrite levels in water and wastewater. These tests help assess the impact of agricultural runoff, industrial discharges, and wastewater treatment processes on water quality. An advanced spectrophotometric method using mesoporous silica nanospheres has been developed for the sensitive and rapid determination of nitrite in wastewater, demonstrating its importance in environmental protection (Abou-Melha, ChemistrySelect, 2020).</li>
